Definitions
- the present invention relates to a filtration membrane module comprising a filter housing having a first connection and a second connection, and being provided with a membrane compartment in which is mounted a bundle of filtra- tion membranes, which filtration membranes at both ends of the filtration membrane module are cased in membrane holders.
- a filtration membrane module is already known in practice.
- capillary or tubular filtration membranes are mounted in a filter housing and at the ends of the filter housing the filtration membranes are cased in membrane holders closing off the space between the filtration membranes and the filter housing.
- a fluid to be filtered is passed through the capillary or tubular filtration membranes and the fluid passing through the membrane wall, the permeate, is discharged from the filtration membrane module via one or more openings provided in the wall of the filter housing.
- the disadvantage of said filtration membrane module is that there is a strong flow of fluid to be discharged to the opening (s) in the wall of the filter housing, which flow runs partly transversely to the filtration membranes . This results in a strong transverse force being exerted on the walls of the filtration membranes attempting to push the filtration membranes through the openings in the wall of the filter housing.
- Said transversal forces may squeeze the capillary or tubular filtration membranes, so that fluid becomes unable to flow through the filtration membranes, reducing the capacity of the filtration membrane module. In addition it is very likely that the filtration membranes become damaged and possibly become leaky.
- the rinsing procedure for the filtration membranes is far from optimal. Rinsing is necessary because after a time the filtration membranes become saturated with components from the fluid to be filtered.
- the distributor openings in the distributor pipes extend substantially in the longi- tudinal direction of the filtration membrane module. This embodiment prevents a permeate flow in the circular direction in the filtration membrane module, which would be directed transversely at the filtration membranes. This contributes to a further reduction of the possibility of damage and squeezing of the filtration membranes and therefore to a further increase in capacity.
- the surface area of the distributor openings in the distributor pipes increases radially outward from the centre of the filtration membrane module.
- the ratio between the flow-through area in the distributor pipe and the filtration membranes can be kept constant as a function of the radial distance to the centre of the filtration membrane module. This ensures a further improvement with regard to the permeate flowing parallel to the filtra- tion membranes.

- Fig. 6 shows a cross section of the third preferred embodiment shown in Fig. 5; ⁇ ⁇ to to H P>
- the membrane holders 30 comprise a resin applied in the filtration mem- brane module, in which the filtration membranes 21 are imbedded. At the two ends of the filtration membrane module the filtration membranes 21 are open. The unsealed ends of the distributor compartment 40 function as outlet 42.
- Distributor pipes 50 are mounted to pass through the tube 45. These distributor pipes 50 are arranged substantially perpendicularly through the tube 45 and are provided with distributor openings 51. In the first embodiment shown in Figs. 1 and 2, two adjacent distributor pipes 50 are always rotated 60° in relation of each other, as can be seen in Fig. 2. Between the distributor pipes 50 shown in Fig. 1, there are two further distributor pipes 50 which are rotated 60° and 120° in relation to a left and right distributor pipe 50 respectively. The number of distributor pipes 50 necessary will depend on the particular application to which the fil- tration membrane module is put and on the filtration properties of the filtration membranes.
- a second embodiment is shown in Figures 3 and 4.
- This second embodiment is largely identical to the first embodiment.
- holders comprising, for instance, a resin
- Said holders completely seal the ends of the filtration membrane module, but not the filtration membranes 21.
- the distributor compartment 40 is in communication with the outlet 42 pro- vided in the wall of the filter housing by means of pipes 60.
- Said pipes 60 may be designed as distributor pipes 50, but they may also lack distributor openings 51.
- Figs. 5 and 6 show a third preferred embodiment of the filtration membrane module according to the invention.
- the distributor compartment 40 is formed between the filter housing 10 and a tube 46 mounted in the interior of the filter housing 10.
- Said tube 46 holds the filtration membranes 21 and at the ends of the filtration membrane module the filtration membranes are cased in mem- brane holders 30, closing off the space between the filtration membranes 21 and the distributor compartment 40, that is to say the tube 46.
- the membrane holder 30 may be formed by a resin provided in the tube 46.
- the unsealed ends of the distributor compartment 40 function as outlet 42.
- Distributor pipes 50 are mounted to pass through the tube 46, which project into the distributor compartment 40 and which are provided with distributor openings 51.
- the dis- tributor pipes extend substantially perpendicular to the tube 46 and thus also to the distributor compartment 40.
- two adjacent distributor pipes 50 are always rotated 90° in relation to each other, as can be seen in Fig. 6. Between the distributor pipes 50 shown in Fig. 5, there is one further distributor pipe 50.
- the tube 46 may also be fixed in the filter housing 10 with the aid of the distributor pipes 50.
- a fourth preferred embodiment is shown in Figs. 7 and 8. This embodiment is largely identical with the third embodiment. However, in this case holders comprising, for instance, a resin, are provided over the entire cross section of the two ends of the filtration membrane module.
- Said holders serve as membrane holders 30 and holders 31 for the tube 46 in the filter housing 10, the holders completely sealing the ends of the filtration membrane module, but not the filtration membranes.
- An opening provided in the wall of the filter housing 10 functions as outlet 42.
- a fluid to be filtered is fed through the inlet 22 into the filtration membranes 21 of the filtration membrane module of the preferred embodiments.
- the fluid is able to pass the membrane wall, except for one or more components in the fluid which are unable to penetrate the ⁇ w to t P> H in o in o in o L ⁇
